摘要
The failed total knee arthroplasty is a challenge to the surgeon and the patient. Infection, bone loss, and instability lead to a chronically painful and dysfunctional limb. Two-stage revision arthroplasty has been successful in clearing a majority of periprosthetic joint infections. However, there are many cases when the multiply revised and infected total knee arthroplasty cannot be salvaged. We report, a review of knee arthrodesis and a novel technique to manage significant bone loss. The use of trabecular metal cones and a long intramedullary nail can be used in concert with an autologous intramedullary bone graft to provide a stable, length restoring construct with sufficient biology to heal very large bone voids. With this technique we have successfully restored function and stability in the failed knee arthroplasty.
